Overview
The AU1PJ-M3/84A is a surface mount ultrafast avalanche rectifier from Vishay General Semiconductor, housed in an SMP (DO-220AA) package. It features a maximum repetitive peak reverse voltage of 600 V and an average forward current rating of 1.0 A. The device exhibits a typical reverse recovery time of 75 ns and supports a non-repetitive avalanche energy of 20 mJ at an avalanche current of 1.0 A. Maximum ratings include a peak forward surge current of 25 A and an operating junction temperature range from -55 °C to +175 °C.
Feature Summary
- Ultrafast recovery characteristics optimized for high-frequency switching applications
- Glass passivated pellet chip junction providing robust reliability
- Avalanche-rated capability supporting non-repetitive energy dissipation
- Low profile design suitable for automated placement processes
Applications
- Secondary rectification in AC/AC converters
- Freewheeling circuits in DC/DC converters
- High temperature consumer electronics power supplies
- Automotive electronic control units
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements. The M3 suffix indicates halogen-free and RoHS-compliant commercial grade construction, while the HM3 suffix denotes automotive grade material categorization. Confirm that the package code matches the required reel diameter and quantity specifications for your manufacturing line.
Selection Notes
Select this component when designing circuits requiring fast switching speeds and high thermal stability. The 600 V blocking voltage makes it suitable for medium-voltage secondary rectification tasks. Ensure the application environment remains within the specified -55 °C to +175 °C operating junction temperature range to maintain performance integrity and longevity.
Part Context
This part belongs to the eSMP series of surface mount ultrafast avalanche rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, such as AU1PD through AU1PM, all sharing the same DO-220AA footprint. These components are designed to replace bulkier through-hole alternatives in compact modern power supply designs.
Replacement Considerations
Direct substitutes within the same family include AU1PG-M3/84A (400 V), AU1PK-M3/84A (800 V), and AU1PM-M3/84A (1000 V). Automotive-grade equivalents are available with the HM3 suffix, such as AU1PJHM3/84A.
